Firefox 11: Cannot access memory at address 0x0
molnarg opened this issue · comments
I get this error when trying to use unmask_jemalloc for Firefox 11:
(gdb) jechunks
[unmask_jemalloc] parsing structures from memory...
warning: value truncated
Python Exception <class 'gdb.MemoryError'> Cannot access memory at address 0x0:
Error occurred in Python command: Cannot access memory at address 0x0
Is this version of firefox too old and unsupported by the current version of unmask_jemalloc?
Actually the first version of unmask_jemalloc was tested on Firefox 11. I'll try to take a look. Are you trying on Linux? 32 or 64 bit system? GDB version?
Thanks for looking into it! I'm on 64 bit Linux system, debugging a 32 bit Firefox 11 with GDB version 7.6.1-46.fc19
Oops, I totally forgot about this, sorry!
If you're still interested, I just pushed changes that worked for me on Firefox 11.0 with gdb 7.7 (which embeds python3).
This was required for a project of mine, and do not really need this capability anymore. But thanks for updating the code. I'm sure I will find this useful sometime in the future :) Now closing the ticket!
